FPHOTOGRAPHIO-PRINT-ING DEVICE- l atented Feb. 20', 1906.

Be it known that I, WILLIAM H. Bnowrna citizen of the United States, residing at Lockhart, in the county of Caldwell and State of Texas, have invented a new and useful Photographic-Printing Device,of which the following is asp'ecification.

This invention relates to photographicprinting apparatus, and has for its main ob-- ect' to provide an improved ap aratus of this character whereby the chargingof the apparatus with the developing-paper and the process of rinting u on the paper may be convenient y, successfiilly, and ex editiously carried on without the aid-0f a dark room.

It is also proposed to arrange the device for printing .from glass negatives and also from films.

Another object of-the invention is to provide for conveniently making a succession of exposures upon a continuous roll of print-paper, this feature being particularly advantageous in printing anoramic views.-

Other ob 'ects o the invention reside in the provision of novel means for supportingthe develo in -paper within the case of the a paratus or shifting thepaper-holding'mec anism so as to bring the aper into snug contact with the negative, or fi m during the exposure period and to withdraw the pa er therefrom to permit shifting of the latter or presenting a new surface to be exposed and to provide for conveniently inserting an unexposed roll of print-paper and for removing the roll of pa- .per after exposure in a simple and expeditious manner.

With these and other-object's in view the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawin s, and particularly pointed out in the appen ed claims.

In the accompanying drawings, Figure 1 is a perspective view of a 'hotographic-printing apparatus embod ing t e features of the present invention. ig. 2 is a central sectional view thereof. Fig. 3 is a sectional view on the line 3 3 of Fig. 2. I Fig. 4 is a sectional view on the line 4 40f Fig. 3.

Like characters of reference designate corresponding parts in each and every figure of the drawings.

The case 1 of the present apparatus is preferably rectangular in sha' e and of suitable proportions, according to t e size of negative to be accommodated. In the top of the case there is a rectangular o ening surrounded by an upstanding rim or ange 2, which is embraced within a light-excludingcovering 3, of

felt or other material, said opening constituting the exposure-opening through whichthe negative is-designed to be exposed.

Within the' case there is a roll jholdin frame or carrier for the support of the roll 0 print-paper, saidf rame or carrier comprising a metallic back or plate 4, which is beaded at opposite edges, as at 5 and '6, so as to form rounded corners aroundwhich thev rint-pa- I per is designed to ass, so as to avoi damage thereto, as will'be ereinafter'ex'plained. The

other unbeaded ed es ofthe, back plate are provided with pen ent sides 7 and 8, which are provided at their lower edges and substantiall 'midway'between their ends'with outward y-directed flanges 9 and Y10, there being a comparatively narrow cross plate or bar 11 secured to the under sides of the flanges 9 and. 10 and projectingbeyond the sides 7 and S with its ends upturned to-form slides 12 and 13, working in correspondin guideways formed upon the inner faces of t e adjacent sides of the case, preferably by'means of spaced metallic strips 14.

As best indicated in Fig. 2 of the drawings, it will be noted that the length of the plate or back 4 between its beaded edges exceeds the corresponding dimension of the exposureopening in the top of the case, while upon referenceto Fig. 3 it willbe noted that the other dimension of the paper supporting back 4 is somewhat less than the other dimension of the exposure-opening. At the center of the cross-bar 11 there is a fixed nut or internally-threaded bearing 15, piercing the cross-bar'for the receptionof an adjusting-screw 16 which is swiveledin a bearing 17 upon theiexterior of the bottom of the case, so that by mani ulating the exposed head or finger-piece of the adjusting-screw the paper-holding frame may be fed toward and away from the exposure-openin A paper-roll holder 18 is mountedietween the left-hand ends of the sides 7 and 8 of the paper-holding frame or carrier, said roll bemg in the nature of a s 061 having a flange or head 19 at each end,an each endbeing further provided with a socket 20 for the reception of a suitable 'ournal or pivot-pin 21, carried by a spring p ate or arm 22, having one end soldered or-otherwise secured to the exterior of the adjacent side of the paper holder or carrier with the pivot passing through a per foration in said side and received within the socket, whereby the spool or roll is rotatably supported in place. Each end of the roll or s )001 is mounted in the same manner, and there is a swinging guard or keeper 24 ivoted upon the exterior of the adjacent si e of the aper-holder and designed to lie across the free end of the spring-arm 22, so as to maintain the pivot 21 in the socket of the roll or spool. By swinging each of the guards or keepers 24 away from the adjacent spring-arm 22 the latter may be forced outwardly, so as to withdraw the pivot from the roll or spool, and thereby ermit convenient removal and application t ereof.

Opposite the roll-holding spool 18 there is a similar receiving spool or roller 25, which is provided at each end with a head 26 and is tubular in form for the reception of a shaft or supporting-bar 27, which pierces the side 7 of the paper-holder and is carried by a slide 28, covering an opening 29 in the adjacent side of the case and working in a guideway 30 upon the exterior of the case, there being a button or finger-piece 31 provided upon the outer end of the rod or shaft for convenience in rotating the same. As best shown in Fig. 3, it will be noted that the slide 28 is provided with a tubular bearing 32, in which the shaft or bar 27 is rotatably su ported. Op-

7 posite the finger-piece end 0 the shaft or caring 27 the spool or roller 25 is provided with a washer 33, which has lu s or projections 34, taking into corres on ing seats or notches in the adjacent en of the spool, so as to interlock the washer and the spool, the washer having a threaded opening for the reception of the threaded terminal 35 of the shaft or rotatable bar. As indicated in Fig. 4, it will be noted that the adjacent end portion of the side 8 is cut away, as at 36, so as to expose the adjacent end of the roller 25 to receive the projections 34 of the washer 33, there being a spring-arm 37 secured to the side and overlap ing the cut-away portion and also providerf with an opening 38, forming a bearing for the reception of the threaded terminal of'the shaft, the spring constituting'a tension device or brake to prevent looseness of the roller or spool. The printpaper 39 is of course put up in the usual manner upon the spool or roller 18 and is secured to a backing-tape 40, as usual, each end of the tape being projected a suitable distance beyond the print-paper, so as to permit of said projected portion of the backing being secured to the receiving-roll 25 without ex osing the print-paper. As usual, the bac or exposed side of the backing-tape is provided with a series of numerals indicating the successive sections of the print-paper.

To enable the insertion of the spools or rolls 18 and 25, the bottom of the case is provided with the res ective o enings 41 and 42, which are norma 1y close by the slides 43 and 44, each slide being provided with a central opening covered by a ruby glass 45 or other transparent material which will exclude actinic rays of light from the interior of the case and at the same time permit of the convenient examination of the numbers upon the back of the backing tape or web. It will here be explained that the print-paper is originally wound upon the spool 18 with its sensitized face wound next to the spool and the web or backin -tape upon the outer side, whereby the num ers upon the back of the web can of course be seen through the glass 45.

In charging the apparatus a full roll or spool of print-pa er and an empt roll or spool are mounte upon the aper older or carrier, the free end of the ackin -web of course being drawn around the bea ed edge 5 of the paper-supporting plate or table 4 across the upper face thereof, and thence around the opposite beaded edge 6 of theplate or table anriconnected with the empty spool 25, this operation of course being ac complished without exposing the print-paper by reason of the fact that the web is proj ected a sufficient distance beyond the outer end of the print-paper to enable the connection of the web with the empty spool 25 without unrolling any portion of the paper.

After the apparatus has been charged with a roll of print-paper the cut-off slide 46 is thrust inwardly through the slot 47 in the righthand side of the case across the top of the paper-supporting plate or table 4, the interior of the case being provided at opposite sides with guideways 48 for the reception of the edges of the slide, whereby any light entering through the exposure-opening in the top of the case will be effectually excluded from the unexposed portions of the printpaper when being fed from the full roll or spool 18 to the receiving-spool 25 when the latter is rotated by manipulation of the finger-piece 31.

The negative-holding element of the present device consists of an open rectangular frame 49 of a size to fit snugly within the exposure-opening in the top of the case with the upper portion of the frame projected at opposite ends to form ledges 50 to rest upon the top of the flange 2, and thereby support the negative-holder in the exposure-opening. At the flanged ends of the negative-holder there are also internal flanges 51 at the bottom of the holder for the support of a negative or a glass plate, such a plate being illustrated at 52. The glass plate 52 is a piece of ordinary transparent glass, preferably bound around its edges with some suitable black light-excluding material 53, said glass plate being employed when printing from a film; but when printing from a negative plate said plate takes the place of the transparent late 52. The open top of the negatlve-hol er is capable of being closed by a shutter 54, havin one end hinged to the top of the ne ativeho der, as indicated at 55 in Fig; 3,- w ereby the shutter is adapted to close down upon the external led cs 50, each longitudinal edge of the shutter being provided with a grooved flange 56 to receive the up er edge of the negative-holder and exclude ight from the interior thereof. The hinged end of the shutter is provided with a crank-handle 57 for convenience in opening and closing the shutter. At each end of the negative-holder there is an eye 58, designed to be received between corresponding eyes 59 upon the exterior of the flange 2, there being a suitable pin 60 capable of detachable engagement with the alined eyes to removably retain the negativeholder in place.

In practice the device is charged with a roll of print-paper, as hereinbefore described, the cut-off s ide 46 bein pushed in, so as to exclude li ht from the lower portion of the interior 0 the case. 'The negative-holder is then fitted in lace, the shutter 54 opened, a

negative fitte in the place of the lass plate 52, and the shutter then closed. he receiving-spool 25 is then rotatedby manipulation of the fin er-piece 31 until the numeral 1 appears t rough the sight-openin in the bottom of the case, which indicates t at the first section of the print-paper is upon the upper face of the paper-supportin plate or table 4. The slide 46 is then with rawn, the screw 16 manipulated to raise the carrier until the rint-paper is brought into engagement with the ne ative, after which the shutter 54 is opened y means of the handle or finger-piece 57, so as to expose the negative for the desired length of time, whereupon the shutter 54 is closed, the screw 16 manipulated to withdraw the carrier from the negative, the slide 46 pushed in, and the fingerpiece 31 manipulated to wind the exposed portion of the print-paper upon the receivingspool 25. 5

When rinting from a develo ed film, as shown in ig. 2 of the drawings, it will be explained that the negative-holder 49 is removed from the exposure-openin the film 61 placed across the opening, an then the negative-holder is replaced, thereby forcing the film down into the opening and drawing the same snugly across the bottom of the negative-holder, whereby the film occupies substantially the same position as that of the negative-plate and the printing operation is proceeded with ashereinbefore described. After one exposure has been made the negative-holder may be loosened, so as to ermit of the film being shifted sufficiently to rin the next succeeding negative portion 'thereo into alinement with the exposureopening of the case and the printing operation re eated, from which it will be understood t at the present printing device is especially effective when printing panoramic views, as the views may be accurately matched in a very simple and expeditious manner. 5
